BTCA couldfully crosslink with the fabric and the silica ?lmalso improved the ?exibility of the fabric. Compared to Method 1, in Method 3, the paddedBTCA ?nishing solution was only dried and then34567pH891011padded with silica sol. The BTCA available waslesser. In Method 5, the sample which paddedFig. 6. E?ect of pH values on the tensile strengths offabrics treated with MPTS mol/L and concentrationof the sol 100%.in alkaline medium. That might be because the overrapid speed of hydrolysis of TEOS in higher pH leadto uneven distribution of ?lm onto the fabric surface. The higher the pH value of the sol, the higherthe speed of the hydrolysis. That might result ingreater uneven distribution of ?lms. When an external force was imparted, the resulting internal stresswould concentrate on the weaker areas. Then the tensile strength would decrease with the increase in thepH value.. Processing methodsThe sequences were illustrated in Table 1. In Fig. 7,the crease recovery angles of the samples ?rstly ?nished with BTCA (Methods 1, 3 and 5) were higherthan those ?rstly treated with silica sol (Methods2, 4 and 6). That might be because with Methods 1, 3 and 5, BTCA could better crosslink withthe fabrics. Whereas with Methods 2, 4 and 6,for the obstruction of the silica sol, BTCA could280260240220200with BTCA ?nishing solution was directly paddedwith silica sol solution. The BTCA available forcrosslinking with the fabric was much lesser andwas likely to weaken the e?ect of the anticrease?nishing.In Fig. 8, samples treated with Methods 1 and 2seemed to have much lower tensile strengths thanother processes. This might be attributed to thetwo times of curing. When curing at 160?C, theglucopyranosyls of cellulosic macromolecular chainsbegan to dehydrate, the degree of the cellulosicmacromolecular chains decreased and the numbersof the carbonyls and the carboxyl increased. Thesewould result in the decrease of the tensile strength.However, pared to the one only treated withBTCA, the tensile strength of the sample treatedwith Method 1 was also increased by about %for the existence of the silica ?lm anchored on thesurface of the fabric. Compared to Method 1, inthe existence of MPTS, silica ?lm in Method 2could better crosslink and anchor to the fabric. Thesilica ?lm had positive e?ect in improving the tensile strength of the fabric.
